When you are looking for the median, you are looking for the middle. So those numbers 12377901, first you would have to put them into numerical order. Which would be 0,1,1,2,3,7,7,9. An easy way to solve it from there would be to cross out each end. Making it 1,1,2,3,7,7. Keep doing that until you either have only one number left, or you have two numbers. In this equation you would have to numbers left, so you would look for the middle of those two numbers which would be 2.5. And there you have found the median of those numbers.
